thanks for the advice, I will probably try some velcro. One of the problems is that they have some holes in the right place, just the wrong shape holes and because the holes are reinforced with plastic and don't fit over the lugs in the floor they stick up... might try some surgery on the mats and see what I can do.
Mind you I would have to be quite drunk to buy these rear seat covers
